Create city pages for new counties and catch-all page

What was done

• Created 10 city pages using the placeholder template across 4 new counties:
  • Owyhee County: Homedale, Marsing, Murphy
  • Elmore County: Mountain Home, Glenns Ferry
  • Blaine County: Hailey, Ketchum, Sun Valley, Bellevue
  • Boise County: Horseshoe Bend, Idaho City
• Created the other-cities-and-counties catch-all page with “Beyond the 24” messaging, a list of additional Southern Idaho counties, and a CTA linking to /contact/?topic=project

Why

These counties and cities are part of the expanded service area structure. City pages use placeholder content (TODO notes) pending future city-specific copywriting. The catch-all page captures traffic for jurisdictions not explicitly listed.
